How to recycle the waste clothes, Fabric, Textile Using the Crusher machine and shredder Machine?

Environmental issues caused by waste textiles

Today's unpredictable fashion trends have also accelerated product obsolescence. The clothes that were originally "new three years old, three years old, sewn up for another three years" have also become fast-moving consumer goods, and they will be thrown away within a few seasons. However, there are very few companies that recycle used clothes worldwide, causing most used clothes and even donated clothes to end up in landfills. Take China as an example, every year 10 million tons of waste or idle textiles are added to be treated, but the recycling rate is less than 15%.

Whether it is growing cotton or producing blended fibers, it requires a lot of energy and water. Therefore, the textiles piled up into mountains every year are discarded without recycling, which is a great waste of resources.

In addition, the textile industry's carbon emissions account for 10% of the world's total emissions, making it the second most polluting industry in the world. However, there is still no efficient recycling technology for cotton or mixed textiles. Every second, textile filled with garbage trucks are being landfilled or incinerated. Although this kind of processing method is very convenient, it also makes clothing quickly become a source of environmental pollution.

Waste clothing becomes building materials

Seeing that more and more waste clothes are piled up, the waste of resources is increasing day by day, and scientists can't sit still. Recently, researchers have proposed a new method of turning waste into treasure, using waste clothing as raw materials to make fireproof and waterproof building materials.

This new method of recycling used textiles was proposed by Professor Veena Sahajwalla and her colleagues at the University of New South Wales, Australia. They collected textiles from the textile industry waste, first removed the zippers and buttons on the clothes, and then crushed these cotton, wool, polyester, nylon, and other fabrics together with a shredder or shredder into a pile. Fiber, and then add chemicals to make the different fibers stick together. Finally, the fibers are compressed at high temperatures to form a solid panel.

Textile fiber reinforced composite materials made from waste textiles

This reuse method is easy to operate, the entire process consumes low energy and is non-toxic. In addition to using a coupling agent, no other chemical reagents are added for pretreatment and coating, which can be said to be very environmentally friendly.

This fiber-reinforced composite material combines and enhances the characteristics of its raw materials: cotton fiber has excellent moisture absorption performance, and its toughness and elasticity increase by 5% when wet; wool has good elasticity; polyester fiber has hydrophobicity and high strength; Nylon fiber has high toughness and good elasticity.

These panels are therefore moisture-resistant and as sturdy as wood chipboard, so they can be used for load-bearing purposes; they are also flame-retardant due to the addition of fine wood chips. And, such materials of different compositions have their own texture and color like wood, ceramic or stone. Therefore, they can also be used for interior decoration such as floor tiles, wall panels or ceilings.

The new study was published in the Journal of Cleaner Production. The paper writes that this series of plates "consists of a non-toxic, low-cost, low-carbon building material." Researchers are working to expand the production of this material.

It is hoped that this material can be applied to production and life as soon as possible, and it can really alleviate the waste of resources and environmental pollution caused by waste textiles.

Blended waste textiles are shredded, crushed to produce flame retardants, pressed into molds to be pressed into automotive panels, air-conditioning sound insulation materials; or shredded and functionalized into wall insulation materials.

The third is to reduce waste polyester clothing to monomers and reprocess it to produce polyester fibers, or alcoholysis and regeneration functional fibers to make high-heat-keeping and memory-filling materials for the home industry.
